IMPROVEMENT IN LUMBER-CARS.

Specification forming part of Letters Patent No. 167,121, dated August24, 1875; application filed July 17, 1875.

To all whom it may concern:

Be it known that I, JAMES L. RIDGELY, J r., of' Harrisonville, in thecounty of Baltimore and Stateof Maryland, have invented a new andImproved SelfDischarging and Resetting Lumber-(Jar and I do herebydeclare that the following is a full, clear, and exact description ofthe same, reference being had to the accompanying drawing, forming apart of this specification, in which Figure l is an end elevation Fig.2, a vertical crosssection Fig. 3, a longitudinal side elevation; Fig.4, a plan view.

The invention relates to cars or trucks whose wheels run upon a track totransfer lumber out of the way after it has been sawed, and to aconvenient place for piling it up.

This invention will first be described in connection with the drawing,and then pointed out in the claims.

A A represent a suitable track extending from the mill to the yard orlocality where the lumber is piled. B represents the horizontal frame onwhich the lumber is loaded, so as to come into contactwith thecross-bars B B B This is providedwith end pieces I) I), made downwardlyangular in form, and having a rod, 0, passing nearly through the an glesvertex, as well as through the fixed bolsters D D of truck, the frame Bbeing thus pivoted to the truck longitudinally on a median axis. Underthis pivoted connection of frame and truck, ifa greater weight of lumberis placed on one side than the other, and the frame is not in somemanner locked to the truck, the heavy side will tilt and cause the loadto be discharged on that side. Before, however, the load is placed inposition the frame B is lock ed by catch-arms E E, having shoulders e ethat press on the truck-floor a, pivots e that allow outward movement,and a connectingspring 6 that draws them toward each other.

Being thus locked the frame is loaded more heavily on the side which isintended to dump, and then the truck run out to its destination. G is alongitudinal slide-bar working through and guided by the fixed bolstersD D, and held forward by a spring, g, so that the cam H will not touchthe arms E E. The projecting end 9 of slide-bar is then made to strike astud or other stop, I, so as to force out laterally the arms E E, thusunlocking the frame from the truck and allowing it to tilt. Theplate-springs J J may be used at each end to assist in holding the frameB in a horizontal position, while other means than those described maybe employed for operating the slide-bar without departing from theprinciple of my invention. 7

Having thus described my invention, what I claim as new is 1. Thecombination with a truck, running on a suitable track, of aload-receiving frame, B, having cross-bars B B B that form the hearingof load and pivoted on a median axis to said truck, as shown anddescribed, whereby the lumber may be dumped by its own weight in themanner specified.

2. The combination, with truck and laterallytilting frame, of arms E E,pivoted at c, having shoulder e, and connected at lower end by spring,as and for the purpose set forth.

3. The combination, with locking-arms E E of the spring-held slidebar,having cam H movable at the time, in the manner and for the purposespecified.

The above specification of my invent-ion signed by me this 23d day ofJune, A. D. 1875.
